' To allwhontit may concern:

Be it known that l, HAROLD J. lBnAn'r, a the hub 1- against the flange 2 is a disk body ,fissansing a peripheral flange 2 and surrounding citizen of the United States of America, held by a detachable member 3 and nut 'residlng at Rochester, in the county of Oakequipped bolts 4: or other fastening means, W.

a land and State of Michigan, have invented so that the disk body is fixed relative to the certain new and useful Improvements in hub.

Demountable Rims for Vehicle Wheels, of which the following is a specification, reference being had therein to the accompanyw in'g drawings.

My invention has reference to that class The disk body is designated 5 and outside of its -central portion, which is held bythe' hub, said disk body is dished or convexo F concave so as to provide a yieldable web portion which includes a curved wall 6 and i quickly replaced by another tire.

Considering withdemountable rims permitting or a this wall in cross section it is at an obtuse punctured or injured tire being easily and angle relative to the axis of the hub l and W at an acute angle relative to the plane of The primar object of my invention is rotation of the wheel and when pressure is to provide a isk with a radial expansible brought to bear centrally of the disk body flange or periphery on which a tire support for instance by a load supported by the hub ing rim/may bemounted and safely held 1, the disk body possesses a degreeof reit 0 against lateral displacementand circumfersiliency since it may be sprung to have the ential creeping during rotation of the wheel. curved wall 6 flexed inwardly and the in- Another object of my invention is to pro- 'clined wall 7 outwardly, this taking place vide a disk wheel body on which a tire supat diametrically opposed points in a plane A porting rim may be mounted and novel ata right angle'to the plane of the load deen t fasteners are carried by the disk body'for pression on t engaging the tire supporting rim to .posie disk body. The peripheral edges of the'annular wall trvely secure said rini relative to the disk body.

or web 7 are integral with a flat wall 8 in the plane of rotation of the wheel and said A lurther object ofthis invention isto flat wall has an inturned annular flange 9 W accomplish the above results by a metallic having its edge notched, split or otherwise wheelstructure possessing a desired degree, cut away, at intervals,.- as at 10, thus ercl resiliency and the construction entering mitting of the flange 9 being tontracte or into the wheel will be hereinafter speci'ficaldistended. Tn pressingflollin or otherwise L ly described and then claimed. 1 producing the -disk bo the lange 9 is disit ldelerence will now be" had to the draw. posed at an obtuse ang e relative to the hat in wherein wall 8, such angle approaching that ot a Figurel is a vertical sectional view oi right angle relative to the wall 8, so that a wheel in accordance with myinvention;

Fig. 5 is a perspective view of a portion of the tire supporting rim; Fig. 6 is a similar view showing an air W tube for a tire; j i Fig. 7 is a perspective view ot a detached fastener, and Fig. 8 is aside elevation eta detached diskbody. Y W Tn the drawing, the reference numeral 1 denotes a conventional form of hub havis an enlarged .,view of the same the flange 9 may be forcibly contracted to assume a position at substantially a right at angle to said wall and when'the flange is; undersuch compression or retraction it has an inherent tendency toradially expand and produce anoutward radial'pressure which is taken advantage of for anchoring a tire the supporting rim 11 on the disk body.

The tire su'pporting rimll has the usual and well known clencher edges 12 for re; tainingthe outer casing of a tire on the rim and in forming said riin I provide the its same with an annular inwardly extending bead 13,'Wl1i0h, at intervals, has its outer portion cut away-to provide recesses 14 presenting' three shoulders or walls '15 and 16.

As shown'in Figs-3 and l the tire supmo porting rim 11 maybe laterally forced on to, the flange 9, said flange being contracted and forced into a position substantially at a right angle to the wall 8 and when in such position it produces a constant pressure against the inner wall of the rim 11. The mounting on movement of the rim 11 is limited by the bead 13 engagin the wall 8 and said wall has a plurality or openings 17 to receive non-rotatable bolts 18. On the rectangular shanks of these bolts are placed as fasteners orclips 19-which are non-rotatably held against the wall 8 by nuts 20 screwed on the bolts 18. The fasteners or clips 19 have angular ends 21 engaging the shoulders and 16 of the recesses 14: with the 16 shoulders 15 preventing lateral displacement of the rim 11 and the shoulders 16 prevent- Y ing circumferential creeping. The tire supporting rim 11 is positively anchored relative to the disk body and by loosening the ac nuts the fasteners or cli s 19 may re- .cede or be manually retracte to permit of the rim 11 being withdrawn from the periphery of the disk body.

The rim 11, flange 9 and wall 7 have opena 25 ings, as shown in Fig. 6, providing clearance for a tire inflating tube or connection 21.

One embodiment of my invention has been illustrated, but it is to be understood that so the structural elements are susceptible to such variations and modifications as fall within the scope of the appended claims,

What'l claim is 1. In a disk wheel a disk body having an annular split expansible flange, and a tire supporting rim adapted to be mounted on the flange of said disk body to contract said flange so that its expansive force will bind said rim on the disk body.

2. As a new article of manufacture, a disk body portion adapted for use as the disk of a disk wheel formation and wherein the tire supporting rim and disk are adapted to have a mutual gripping relation therebetween, such disk body having a flange portion of greater diameter than the internal diameter of the rim to which it is applied and having a configuration which permits the flange to be reduced in external diameter by the r assembling of rim and disk, the change in flange diameter by the assembly producing an expansive force characteristic to the flange to maintain a. gripped relation between flange and rim.

3. In a disk wheel, a disk body having a wall with an annular split expansible flange a demountable rim on the flange of said body wall and bound thereon by the flange being under compression and fasteners carried by the wall of said disk body and engaging said rim to anchor said rim relative to said disk body.

In testimony whereof I al'fix my signature.
